Obama attempted to move control of the Census Bureau from the Commerce Department to the White House, to be managed by then Chief of Staff Rahm Emmanuel. 6. Obama had provided under the radar amnesty to illegal immigrants by allowing ICE Director John Morton to prohibit ICE officers from enforcing US immigration laws.
The primary enzymes responsible for DNA replication are DNA polymerases. Understanding the activity and limitations of DNA polymerases help in making sense of why DNA replication occurs the way it does. Key points are: 1  Prokaryotic cells contain three different DNA polymerases.2  Each have slightly different activities.uring DNA replication a DNA double helix must unwind and separate so that DNA polymerase enzymes can use each single strand as a template for the synthesis of a new double strand. Strand separation is catalyzed by a Helicase enzyme.
Explain the effect on DNA replication if there is a mutation to the 5' to 3' polymerase. If the 5' to 3' polymerase activist is missing, no dNTPs will be incorporated into the DNA. Explain the defect on DNA replication if there is a mutation on the 5' to 3' exonuclease. 5' to 3' exonuclease is needed for DNA polymerase to remove RNA primers from the 5' ends of Okazaki fragments. If the activity is missing the primers will not be removed from newly synthesized DNA. Explain the effect on DNA replication if a mutation affects the activity of 3' to 5' exonuclease. 3' to 5' exonuclease is needed for proofreading.
